Kerakoll - Biocolor universal mineral joint

Universal mineral joint for joints 2-20 mm with very low content of chemical additives. Protects against discoloration and eliminates efflorescence. Very long machinability with accelerated cleaning ability.

properties

• ekokompatybilna
• does not thicken (constant workability up to 30 min)
• does not collapse (full joint filling)
• full grout (ixotropic, holds shape)
• quick and easy application (extended plasticity under the trowel)
• quick washing (waiting time for finishing 10 min)
• uniform color (selected and stable raw materials)
• abrasion resistance (the purest mineral aggregates)
• early foot traffic (commissioning after 8 hours)
• compact and smooth surface (homogeneous and granular mix)
• insensitive to aggressive waters (very low content of chemical additives)
